DOUBLE MEMBRANE TRANSDUCER PROTECTOR

摘要

A transducer protector including at least two spaced apart filter membranes. The transducer protector may include a body positioned between two tubular connectors, each of which contains an axially aligned lumen. The body lumen may be separated from the lumen of each of the tubular connectors, respectively, by the filter membranes. An indicator may be disposed in the body to alert a user that the filter membrane has been breached by a contaminant so that the user can take immediate steps to prevent further contamination of the system. The indicator may display a change in an absorbance spectra peak at a wavelength ranging from approximately 200 nm to approximately 800 nm upon reacting with bodily fluid.
